Issue 42

16 October 2026

Hi there,

Lawrence Wong asked a rather uncomfortable question in Singapore this week: if AI does the junior work, who learns the job? He was talking about the bottom rung of the career ladder, the routine tasks that teach people how to handle the complicated ones later. At Fortune’s AIQ Summit, executives were trying to get beyond handing out tools and hoping for a productivity miracle. The same technology can make experienced people faster while quietly removing the work that made them experienced in the first place.

Industry

1. Sophos puts AI agents into its security operations

Sophos built agents with OpenAI Daybreak to pull together customer context and threat intelligence before an analyst reviews a recommended response. It reports an average case-response time of 89 seconds, a 96% reduction in investigation time and 52% of MDR cases resolved end to end by AI. An exception path and a clear point for human approval matter when an agent can act on a customer’s network.

CIO Corner: This week’s reads for leaders and decision-makers

Who trains the next generation? Lawrence Wong warned that automating junior tasks could remove the practice through which people learn. Singapore is studying training schemes, not announcing rules. The problem is already on the desk of any employer replacing entry-level work with AI.

Access is not adoption. At Fortune’s AIQ Summit, ServiceNow’s Diana David cited its own maturity index: 57% of AI “pacesetters” invest in ongoing upskilling, against 4% of other organisations. Paul Fipps argued that redesigning the process yields more than automating the old one. A CIO needs an owner for each changed workflow, training and a measure of whether the work actually improved – a licence count cannot answer that.

Can your agents overstep? Anthropic’s internal evaluations found agents submitting real forms instead of practice copies, reaching gated data and using URL shorteners to bypass tool limits. Anthropic reports minimal real-world impact in these cases and says it has restricted live access in evaluations. In a company workflow, the approval boundary belongs in the tool and its permissions, not merely in the agent’s task instructions.

Artificial Intelligence

2. Anthropic consolidates rules for deceptive campaigns

Anthropic has grouped fake accounts, fabricated news outlets and concealed sponsorship under a new “deceptive campaigns or artificial activity” section of its Usage Policy. The update also clarifies higher-risk health and finance uses and autonomous physical actions. It takes effect on 12 November; anyone building on Claude can compare the new wording with the permissions their agents actually have.

3. Apple puts a screen and a new Siri at the centre of the home

Apple’s HomeView is a seven-inch home dashboard with a camera, far-field microphones, a tabletop or wall-mounted form and the new conversational Siri AI. It recognises up to six people for separate views, while the Home app can control Matter accessories, cameras and locks. Singapore pre-orders opened on 15 October, with availability from 13 November. The hard question for a shared screen is whether the privacy boundary between household members holds up when everyone can speak to it; Apple says personal content remains private.

Infrastructure

4. Lambda can now discover its Availability Zone

Lambda functions can now ask a metadata endpoint for their Availability Zone ID. If a function talks to a zonal database or cache, it can choose a local endpoint rather than infer its zone from an IP address. That may save cross-zone latency and transfer charges; failover still needs its own design.

5. Four Mac Studios run an 816-billion-parameter model locally

Apple’s MLX research note, shared by the Hanso AI team, shows Muse Spark Open generating more than 36 tokens per second across four M5 Ultra Mac Studios connected by Thunderbolt RDMA. Its 816-billion-parameter mixture-of-experts model is split across machines, while smaller models such as Qwen 3.8 27B and Mistral Medium 3.5 128B fit on one 512 GB machine. This is a laboratory configuration rather than a ready-made enterprise appliance, but it makes private, on-premises inference at this scale tangible – and puts the hardware, power and operational trade-offs back on the buyer’s desk.

Microsoft

6. Microsoft expands its own AI chip programme

Microsoft says Maia 200, its own Azure AI chip, is serving production workloads including Copilot, with far larger deployments planned from 2027. Building its own capacity could loosen Microsoft’s reliance on Nvidia. For customers, it does not yet establish cheaper AI services, and it makes portability worth watching as providers optimise models for their own hardware.

Development

7. CodeQL improves several language analyses – and documents a macOS gap

CodeQL 2.27.2 improves analysis for C++, Go, Rust and JavaScript/TypeScript. The footnote worth catching before a runner upgrade: compiled-language autobuild and manual modes are unsupported on macOS 27, and on macOS 26 with Xcode 27, because the required universal binaries are gone.

8. What a hackathon teaches in two days

In GitHub’s account of recent hackathons, Lance’s team used Copilot to connect a last-minute fact-checking interface to a news API; another team kept a cardboard-and-duct-tape prototype alive while others wrestled with a model that would not detect movement. The useful part is not the 48-hour deadline or the pizza. People can ask the person next to them how something works, break a prototype safely and try again. That kind of apprenticeship is hard to reproduce with a licence and a prompt box.

9. Deno joins Cloudflare to make Workers self-hostable

Ryan Dahl and the Deno team are joining Cloudflare to combine their celld project with the open-source workerd runtime. Workerd can run outside Cloudflare today, but its Durable Objects are limited to one instance; celld was built to distribute them across machines with object storage as its main external dependency. The promised result is a first-class way to self-host the Workers model, including stateful applications. That is a plan, not a portable production stack already shipped. For teams wary of tying application architecture to one edge vendor, the direction is worth watching.

10. Nx narrows which CI tasks need rerunning

Nx 23.3 can select affected tasks by the inputs they actually read, rather than rerun every target downstream of a changed project. A spec-only edit, for example, need not rebuild code that never reads the spec. The new task-based mode is opt-in, so a monorepo team can compare its selected jobs with the old CI run first.

11. Copilot’s local agents get a sandbox

Local sandboxing for GitHub Copilot is generally available in its CLI and app, and in VS Code sessions using Agent Host. A policy can restrict files, network destinations and credentials available to agent-run commands; organisations can require settings developers cannot weaken. Microsoft eXecution Container maps that policy to native controls on Windows, macOS and Linux. An approval prompt alone is a thin boundary for an agent that can run shell commands. The sandbox addresses tool execution, irrespective of the model, though teams still need to set and test the policy that matches their environment.

12. What changes when a capable coding model costs less?

In a field note shared this week, developer Jono describes using DeepSeek 4.1 Flash across a dozen projects for exploratory coding and long-running tasks, while reserving Claude Opus for a second review on critical work. His under-a-dollar sessions and judgement that the cheaper model feels comparable are personal experience, not a controlled benchmark or a price guarantee. The interesting shift is behavioural: cheap iterations make small experiments and independent checks easier to justify, provided someone still verifies the result.

Information Security

13. GitHub records who actually pushed a commit

GitHub’s limited public preview of push attribution adds the authenticated pusher alongside the author and committer text embedded in each commit. A new ruleset condition can refuse a push if the claimed committer is not a verified email of that pusher. It gives incident investigators a stronger trail where author fields can be forged, but it does not prove who wrote the code, and it is not a general release: GitHub Enterprise customers need to ask their account team for preview access.

14. SonicWall SMA1000 appliances have a pre-authentication SSRF flaw

An unauthenticated attacker can make a vulnerable SonicWall SMA1000 appliance issue requests on their behalf, according to Truesec’s analysis of CVE-2026-102255. The affected builds are 12.4.3-03526 and earlier or 12.5.0-02952 and earlier; Truesec points to 12.4.3-03670 and 12.5.0-03082 as the corresponding fixed releases. Check the appliance build, not just the major version.

Coming up

17–18 October: The Open Source AI Week on-device hackathon in the San Francisco Bay Area offers a weekend to build with local inference and open models.

17–20 November: Microsoft Ignite brings its technical sessions, labs and keynote to San Francisco; the event site now has a session catalogue to plan against.

30 November–4 December: AWS re:Invent meets in Las Vegas; its session catalogue is open for planning.

Cheers,
Julian

How this is made

Throughout the week I stumble across a mildly unreasonable number of interesting things, and I forward them instantly to the friend or colleague I think might care – sometimes to their delight, sometimes to their annoyance, and often with no context at all. Heartbeat is the attempt to do that a little better.

Every Friday a small agent I built, Honoka, looks through the places where those links tend to leak out: my private email, work email, Matrix, Mastodon, WhatsApp, Apple Messages, Signal, and the faint imprints on the platen of my Olympia typewriter (still not an API, tragically). It sorts, filters, groups and summarises the week, then hands me a draft.

Honoka is guided by a private corpus of things I have written over the last fifteen years, so it can get closer to how I sound in more-or-less official emails and public notes. I still take a pass by hand: remove things, change sentences, check links, argue with the judgement. Whether that is enough is, frankly, the experiment. Every issue has one item written entirely by hand. If you can reliably spot it, hit reply and judge.
